DRINKING-FOUNTAIN FOR IPOULTF Y.

Application filed December 19, 1911.

To all whom it may concern:

Be it known that I, FRANK Enos, Jr., a citizen of the United States,residing in the city of Norwich, county of New London, and State ofConnecticut, have invented certain new and useful Improvements inDrinkin -Fountains for Poultry; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain unprovements in drinking fountains forpoultry, and has for its object to provide a device of this descriptionwhich shall be exceedingly simple and eiiicient, automatic in itsoperation and not at all likely to get outof order. and with these endsin view my invention consists in certain details of construction andcombination of parts hereinafter fully described and then particularlypointed out by the claims which conclude this description.

In the accompanying drawing Figure l is a sectional elevation of myimprovement, and Fig. 2 a detail broken front elevation, partly insection, of the bottom portion of' the fountain.

Similar numerals of reference denote parts in both figures of thedrawing.

1 is the tank or reservoir which is provided at its upper extremity withan exteriorly threaded nozzle 2 whereby water may be introduced withinthe tank, said nozzle being closed by means of a threaded cap 3 adaptedto be driven on said nozzle against a suitable packing ring 4 interposedbetween the bottom edge of the cap and the exterior base of the nozzle.

5 is any suitable bail connected with the tank in any suitable mannerprovided with a handle 6 whereby the tank may be readily transportedfrom one location to another as may be desired.

7 is an air pipe or duct, preferably secured to the outside of the tank,the lower extremity or mouth of said pipe extending within the trough 8which latter is secured to the tank exterior thereof so as to be withinconvenient access of the poultry. This air pipe 7 has no communicationwith the interior of the tank 1 except at the extreme upper end of saidpipe, this communication, in the present instance, being established bymeans of a small pipe 9 i hket Specification of Letters Patent.

which extends from the upper end of the pipe 7 to a point near the topof the tank, for the purpose presently to be explained.

10 is a siphon pipe which is supported by the side wall of the tank 1 insuch manner that one leg of said siphon depends within the tank to apoint near the bottom thereof while the other leg of said siphon dependsexterior of the tank to any predetermined distance within the trough S.

11 is a cross bar from which a conical shaped valve 12 extends upwardlywithin the lower portion or mouthof the exterior leg of the siphon, and18 are spring arms which project upwardly from the ends of this crossbar and snugly embrace the sides of the pipe 7, said cross bar and armsconstituting a yoke which is capable of free sliding movement-s alongsaid pipe, whereby the valve may be operated to open and close the lowerextremity or mouth of said leg.

The operation of my improvement is as follows :WVhen it is desired tofill the tank the valve is elevated so that no water can be siphonedinto the trough 8 and thereby cause the same to overflow, and this wouldof course happen in filling the tank because the removal of the cap 3would supply an ample vent to the tank above the water therein. Afterthe tank has been filled to any desired level, which latter must bebelow the upper end of the pipe 9, the cap is replaced so thatthereafter the tank will be vented solely by the air which passesthrough the pipes 7 and 9. When the valve 12 is depressed water will besiphoned into the trouglruntil the lower end of the air pipe issubmerged, whereupon no air can be delivered at the top of the tank andtherefore the siphoning process will cease. As the water is used by thepoultry, the level of the water within the trough will of course lowerand whenever such level gets below the lower end of the air pipecommunication between the outside air and the top of the tank will beestablished and the siphoning process will continue until the lower endof said pipe is again submerged, and so on.

Of course the upper end of the pipe 7 may communicate with the interiorof the tank merely by means of a small perforation, if desired, but insuch instance the level of the water within the tank would always bebelow such perforation in order not to interfere with the proper ventingof the tank.

But I prefer to have this air pipe in communication with the tank at apoint near the top of the latter in order to permit the tank to bepractically completely filled with water.

The exterior leg of the siphon has been illustrated as housed within thepipe 7 merely as a matter of convenience, since it will. of course beclear that said. leg can extend outside of this pipe so long as itextends within the trough and is properly associated with the valve.

The trough is a simple box-like affair and may extend throughout anysuitable area around the bottom of the tank, this being a mere matter ofpreference.

Whenever it becomes necessary to trans port the tank either to a fillingstation or for any other purpose the valve may be elevated to close thesiphon leg and the trough emptied so as to prevent slopping of thewater.

The trough may rest upon any suitable base it, or, in the winter time,such tank may be supported upon any ordinary heating base to preventfreezing of the water both within the tank and trough.

Havmg thus described my lnvention what I claim as new and desire tosecure by Letters Patent 1s l. A drlnklng fountain for poultry com-)risin a tank. a trou h at the base thereof b 1 b 7 an external air ventcarried by the tank and having one end projecting into the trough andthe other end in communication wit-h the tank above the water leveltherein, a siphon having its outlet leg extending through the air ventfor delivering water from the tank to the trough, and adjustable meanscarried by the vent for controlling the discharge of water from thesiphon.

2. A drinking fountain for poultry com prising a tank, a trough carriedthereby, means for siphoning water from the tank to the trough, meansfor supplying air to the tank, a valve controlling the discharge of thesiphoning means, and spring arms carried by the valve for slidablyengaging the exterior of the inlet of the air supplying means.

3. A drinking fountain for poultry comprising a tank, a trough carriedthereby, means for supplying air to the tank, a siphon for deliveringwater from the tank to the trough, said siphon having its outlet legprojecting into the trough, a supporting base carrying a valve forcontrolling the outlet of the siphon, and spring arms carried by thebase for slidably embracing the inlet end of the air supply means.

it. A drinking fountain for poultry comprising a tank, a trough at thelower portion thereof, an air vent having its lower end n'ojecting intosaid trough and its upper end in communication with the tank above thelevel of the water therein, asiphon having its inlet leg within thetank, and its outlet leg projecting into the trough, and meansadjustably connected to the air vent for controlling the outlet of thesiphon.

In testimony whereof I affix my signature in presence of two witnesses.
